I'm pretty sure one is not an artist until they can draw Spiderman. Throughout all amateur art that image is most statistically prevalent. The simple designs of the series depicting movement and acrobatic conformity pose interesting challenges.

ya, it's supposed to look kinda like waves washing up on the shore.but it's not that apparent, it was a bit of an afterthought lol. she's probably made of water or something.
here's a doodle of a cartoony Rey because she's my favorite!also because i hadn't used my markers yet.

That's really great! I like Finn for his bumbly-ness, but I haven't let it all sit long enough for a definite favorite to show up. And I think that style's great! It'll look good for particular character drawings. (shameless promotion) (sorry)
Wait, no I love TR8R, the one stormtrooper with the melee weapon who attacks Finn and only has one line: Traitor!

awww yeah that weapon was sweet.and honestly i was working on that drawing for your friend but then it somehow got this little brown mark on the paper and i kinda gave up, but i might pick it up again who knows.

oook so I've drawn the picture you asked for :/ I'm not that happy with it admittedly.It's kind of awkward looking because there were so many criteria's, and the "horrible spawn of nightmares monster" is basically just a big snake, but when he said aerodynamic and desert all i could think of was a snake-ish thing.¯\_(ツ)_/¯
Also sorry it has weird smudges and scratches on it, I drew this outside and that wasn't a good idea lol.
This is a pretty rough sketch (like please ignore the entire background) but i still wanted to show it to you so you could tell me if this is maybe the kinda thing he was thinking of?
